[Q] Really Basic Questions

... am very new to this area.. backing up my Nexus 7& rooting it... using an article on 'How to backup your device w/o rooting (using ADB only),' I hit my 1st group of questions... what do I download to... PC or N7? (told you these are really basic)... one of the commands is to specify the packages we want saved... is this asking for the names of the apps? ...or, all the main titles in N7 Settings?... or, ??? I also downloaded an adt bundle (1.2GB) to my PC, in prep for rooting my N7.... is this correct? ... should I actually download it to the N7?? if you can stop laughing long enuff, I could really use the help... tx
